I had stories in two anthologies in 2011 and two (so far) in 2012. I’ve provided the links to Amazon, but all of the anthologies are also available at Smashwords and Barnes and Noble.
If You Leave is in Kiss Me, Kill Me.
Day of Sacrifice is in Dark Tomorrows (2nd Edition).
Surprise, Surprise is in In His Eyes.
Back in Time is in Death By Chocolate.
